#CD05AB

sRGB: 205 / 5 / 171

#CD05AB belongs to the magenta family. Its hex code tells a screen to mix 205 red, 5 green and 171 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 310.2° lands in the magenta region. Its 95.2% saturation makes it strong in color at this lightness. HSL lightness is 41.2% on a scale from black (0%) to white (100%). Of black and white lettering, white has the clearer light-to-dark separation on this background (4.99:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #CD05AB in light and dark. The ratio compares relative luminance, a measure of light weighted for human vision. Identical colors give 1:1 and black against white gives 21:1. A ratio of 2.99:1 falls just below the 3:1 AA minimum for large text. Body text needs at least 4.5:1 because its finer strokes are harder to distinguish.

Black text: 4.21:1

Normal text: Fail
Large text: AA

White text: 4.99:1

Normal text: AA
Large text: AAA

AA and AAA are WCAG accessibility levels. AAA sets a higher bar: 7:1 for normal text and 4.5:1 for large text. Large text begins at 18 pt regular or 14 pt bold. Ratings use the unrounded ratio.

Palettes & scales

Harmonies rotate the hue. Scales mix the starting color with white, black or middle gray in 20% steps in encoded sRGB.

Complementary

#05CD27 sits half a turn (180°) from #CD05AB on the HSL wheel. Keeping saturation and lightness steady while crossing to the opposite hue gives you a contrasting accent. Check text contrast separately before using the pair for lettering.

#CD05AB #05CD27

Analogous

#8B05CD and #CD0547 sit 30° to either side of #CD05AB. The three hues are neighbors on the wheel, so you can change the color of a border or highlight while keeping it close to the original.

#8B05CD #CD05AB #CD0547

Triadic

#CD05AB, #ABCD05 and #05ABCD are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#CD05AB #ABCD05 #05ABCD

Split complementary

Start at #CD05AB and look across the wheel. #47CD05 and #05CD8B sit 30° to either side of its exact opposite, giving you two different accent choices.
